All hospital grade breast pumps are closed systems which is why they can be used by multiple users and why they are considered more hygienic than closed system breast pumps.
The problem with open systems is that the milk can flow into other parts of the breast pump. This means that there is more cleaning to do, and if the cleaning is not thorough, then there is a chance of the breast milk becoming contaminated.
The basic difference between a closed and an open system of breast pump is that closed systems have a barrier which prevents the breast milk from getting into the pumps tubing or motor. This is consider more hygienic.
Cost can be a big factor with hospital grade breast pumps as many of them are not cheap. If you can not afford the top quality pump, the Spectra Baby USA S2 is a very good quality option that is good for the wallet as well and still highly recommended.
